Editing Between you and I (section)

===Supposed causes===
The cause for this particular error is given by such authorities as a kind of trauma<ref name=grammargirl/> deriving from incorrect usage caused by "you" being both nominative and oblique, and the awareness of the possible incorrectness of "me": "People make this mistake because they know it's not correct to say, for example, 'John and me went to the shops'. They know that the correct sentence would be 'John and I went to the shops'. But they then mistakenly assume that the words 'and me' should be replaced by 'and I' in all cases."<ref name=oxford/> In ''The Language Wars'' (2011), Henry Hitchings provides a similar explanation, adding that for many speakers "you and I" seem to belong together,<ref name="Hitchings"/> which is noted also by Kenneth Wilson.<ref name=Wilson/> That the problem typically occurs when two pronouns are used together is widely recognized: "these problems rarely arise when the pronoun [I] stands alone".<ref>{{cite book|last=Manser|first=Martin|title=Good Word Guide: The Fast Way to Correct English - Spelling, Punctuation, Grammar and Usage|url=https://books.google.com/books?id=6142OlLz2q8C&pg=PA157|year=2011|publisher=A&C Black|isbn=9781408123324|page=157}}</ref> James Cochrane, author of ''Between You and I: A Little Book of Bad English'' (2004), gives a similar explanation—in this case, "people"'s feeling some unease with a sentence like "Me and Bill went out for beers"; Cochrane does not, however, mark it as a hypercorrection, and suggests the phrase only came about "in the last twenty or so years"<ref>{{cite book|last=Cochrane|first=James|title=Between You and I: A Little Book of Bad English|url=https://books.google.com/books?id=Wjy-pG2ZIqwC&pg=PA14|year=2005|publisher=Sourcebooks|isbn=9781402203312|page=14}}</ref>—linguist J.

J. K. Chambers investigated the phrase (as well as the closely related "with you and I") in an analysis of the role of education in the grammaticality of English speakers, in this case from Canada. Data from ninth-graders and their parents indicated little regional variation, but a significant variation between children and their parents, showing children were more likely to pick the "correct" pronoun or, in technical terms, to show "[[accusative case]] concord with [[Conjunction (grammar)|conjoined]] pronouns". Chambers's explanation is that the children are likely to have had better education than their parents, and a study from 2008 of seven regions across Canada likewise showed that concord increased as the level of education increased. Chambers investigates a number of explanations offered, and accepts as one reason that the mistake occurs because of the considerable distance between the preposition and the second pronoun.<ref name="chambers"/>
